GPUs (with matlab)

What is the status of my GPUs? nvidia-smi (from UNIX command line)
Compiling GPU-enabled matlab code can take longer than non-GPU enabled code. One piece of code that usually compiles in under a minute took 16 minutes to compile with GPU functionality enabled.
Java is required during compilation to use parfor parallel for loops (for both GPUs and CPUs). Thus you may not compile with the -nojvm flag if you want to use parfor.
Which nodes have gpus? condor_status -const "HAS_GPU =?= True"
